      Historically, Android has only supported 4 KB memory page sizes, which has optimized system memory performance for the average amount of total memory that Android devices have typically had. Beginning with Android 15, AOSP supports devices that are configured to use a page size of 16 KB (16 KB devices).

      Qt for Android should be validated to work with such devices, i.e. it should be ensured that no hard-coded page sizes are used.
